good start. something funky about the processing with strange colors showing up. dont know if you tried to push shadows in post. I would stop down a bit on some, as you seem to have missed focus and not have enough dof in some of them (4, and 8 mainly). Be careful of the spill on the background. you need to move your subject away from the background, esp if you are using black. Move in your light source a little bit. dont know if you have modifiers or not, but a closer light source, and soft box, gives you better catch lights. It is hard to shoot against a black background at times, esp if you subject is wearing black and is black haired, as it is tough to get separation. also you tend to get much stronger shadows, since there is no "fill" light with a black background
I think 2 is awesome, except for the color shifts.
